It actually doesn't, although it is planned. (We have multi-region 
support, but that implies a shared Keystone for both regions.)

No, and that's not planned either.

I think the most accurate short answer here is "no". Of course, I can't 
claim to speak for everyone.

There are some contributions I think we would be willing to accept, 
though. For example, the biggest obstacle to writing AWS plugins is to 
find a way to provide the user's AWS credentials to the plugin securely. 
If we had a solution to the credential problem it would also be helpful 
for multi-cloud in Heat across two OpenStack clouds that lack Keystone 
federation, so I think that would definitely be valuable.

You're definitely not the only ones wanting to drive AWS from Heat, so 
maybe you could set up a separate StackForge project or the like to 
develop a set of AWS plugins.
